[0002] With the progress of the times, the development of science and technology, concrete construction technology has made the buildings rise from the ground. The raw materials of concrete are relatively rough, and it is very inconvenient to process them directly. Therefore, it is necessary to grind and pre-process the raw materials first, and then further process them before they can be put into use. Therefore, the emergence of a vertical grinder for processing concrete raw materials is particularly important.

[0003] To this end, the patent with publication number CN210115107U discloses a vertical grinding machine, including a cylinder body, a base is provided on the upper part of the cylinder body, a motor is installed on the upper end of the base, a grinding shaft is connected to the lower end of the motor through a coupling, the grinding shaft runs through the entire cylinder body, a first grinding disc is fixedly installed on the upper end of the grinding shaft, a second grinding disc is provided at the lower end of the first grinding disc, the second grinding disc is fixed on the cylinder body, a third grinding disc is provided at the lower part of the second grinding disc, the third grinding disc is fixed on the grinding shaft, a plurality of material discharge holes are provided on the third grinding disc, and a fourth grinding disc is provided at the lower part of the third grinding disc. The vertical grinding machine adopts a multi-stage grinding mechanism, which can grind the material step by step.
